Much of New Jersey is coated in snow Friday morning, the last surviving traces of a weak storm that passed by overnight.

Forecasters expect this weekend's winter storm to leave a bigger mark — with the possibility of rain, snow, sleet, freezing rain, high winds, urban flooding and coastal flooding, depending on where you are.

And the entire state can expect a flash freeze on Sunday, with temperatures dipping into the single digits.

New Jersey, fortunately, does not appear to be in the bull's eye of this whopper. In upstate New York and the interior of New England, the snow will be measured in feet.

A surge of warm air, which will be almost immediately wiped from memory by a Siberian air mass later on Sunday, will rescue us here in the Garden State from the crippling snow that is expected elsewhere in the Northeast, according to the latest predictions from the National Weather Service.

Even so, the weekend looks to be washed out all over the state, whether it be torrential rain or patches of blinding snow.

Gov. Phil Murphy's administration announced Friday evening that Col. Patrick Callahan, the State Police superintendent, was prepared to activate the its Emergency Operations Center on Saturday in order to monitor storm conditions through Sunday.

The state Office of Emergency Management (NJOEM) had been in contact with all 21 county emergency management offices and members of the Emergency Response Bureau were working with county governments to address any storm-related needs, the statement read.

The state Department of Transportation was ready to respond with up to 2,500 plows and spreaders.

The coldest air of 2019 will stretch over the region on Sunday evening, dragging temperatures down into the single digits. This deep freeze has the potential to transform whatever snow and rain is on the ground — or wrapped on tree limbs and power lines — into a thick glaze of ice.

Wind gusts on Monday morning will exceed 30 mph, which yields sub-zero wind chills for the start of Martin Luther King Jr. Day. As the storm pulls away, an Arctic high-pressure system is expected to lock in the cold until at least Tuesday.

This storm has been a tricky one for meteorologists, who have found it hard to pin down how much snow to expect from this event versus other forms of precipitation. Precipitation totals will depend on the track of the storm.

Based on forecasts from the NWS, here's what to expect around New Jersey this weekend:

North Jersey

By the end of Saturday afternoon, snow flurries should be widespread. The heaviest bands are likely between 8 p.m. and midnight at the rate of about 1 inch per hour.

Overnight, temperatures will ascend ever so slightly, making the air warm enough to turn the precipitation from snow to freezing rain to sleet and then plain rain, which will be coming down in buckets until daybreak.

Strong winds and potential ice could lead to power outages and will make traveling hazardous.

By lunchtime, a frigid air mass will begin to envelop the area and quickly transition the rain back to snow. There may be enough energy left for another 1 inch or so of snow until the storm winds down at sunset.

The forecast calls for a total of 4 to 7 inches of snow, mixed in with the rain, sleet and ice. Higher amounts of snow — perhaps a foot — are possible in the northwest corner of the state.

A winter storm watch goes into effect for all of North Jersey at noon on Saturday.

If it were to expected to be colder, Central Jersey would be walloped by this storm. Thankfully, that's not the case.

Look for a snow-leaning wintry mix to start sometime in the mid-afternoon on Saturday.

With air temperatures closer to 40 when the storm peaks, this part of the state will be soaked but spared from big snow totals. Somewhere in the neighborhood of 2 inches of rain — the equivalent of 20 inches of snow — will fall between 8 p.m. Saturday and 2 p.m. Sunday.

At the Shore, a glaze of ice is possible — particularly in Monmouth County, and in parts of northern and western Ocean County.

But wind could also pose a problem for coastal dwellers. Gale-force winds just offshore will be dangerous for mariners, and strong winds along the coast could cause localized power outages, according to the NWS.

As the arctic air moves in, the last bit of the storm will transition back to snow. The NWS says to expect about an inch.

On the Shore, expect the precipitation to be almost entirely rain, except at the end when the entire state will be frosty enough to support snow, and freeze any slush or water leftover.

Minor coastal flooding and inland urban flooding is possible Saturday night and Sunday, with river flooding possibly Sunday into Monday.
